I just got the Smarty for x-mas and all I have to say is WOW, I now know what all the hubbub is, the responsiveness is incredible and I am running on the standard Catcher software #5. I have this stacked with my FMS box and holy crap, really unsure about stompin on her cause it feels studid strong. Even without the FMS this makes regular cruising way better than before. Glad I went with this before injectors. Thanks for all the great reviews on this tuner as it is a fantastic product!
